There is a growing need for designing small self-powered devices, able to sense and deliver
accurate information on the eld distribution around or inside complex media for monitoring and
imaging purposes. Industrial, ...

In interferometric radiometry, the correlations between all pairs of radio-frequency (RF) receivers must be performed in order to obtain the scene visibilities. This represents a cumbersome problem in passive imaging where ...

The principle of communication of passive RFID, which relies on the Modulated Scattering Technique (MST) to transmit the information from the tag to the reader, opens a way to enable conventional RFID for sensing purposes, ...

In this paper, a complete set-up to subway radio propagation measurement at L and C Band is presented. This set-up has been tested at a real subway tunnel with a special structural characteristics allowing propagation path ...

In this paper the use of RFID tags for the measurement of physical parameters in a distributed set of points is presented. Experimental results for two different scenarios are presented; the first uses a 2D RFID array to ...

In this paper the use of RFID for EM field
measurement is studied. A novel RFID antenna with high tuning capabilities is presented and measured, and it is used in combination with several RFID IC to measure the EM ...

Many scientific, industrial and medical applications require the measurement of different physical parameters in order to collect information about the spatially distributed status of some process. Very often this information ...

Microwave imaging is a topic of continuous research for its potential in biomedical area and in particular for breast cancer detection. This paper presents a novel multi-frequency differential linearized (FDL) technique ...

The gate-controllable complex conductivity of graphene offers unprecedented opportunities for reconfigurable plasmonics at terahertz and mid-infrared frequencies. However, the requirement of a gating electrode close to ...

A subsurface imaging system based on a terahertz time-domain spectrometer (THz-TDS) is described in this paper. The system performance has been simulated in terms of spatial resolution, penetration capabilities and SNR. ...

THz propagation through materials may reveal unique macroscopic and physical properties of their internal structure without the damage associated with ionizing radiation. The generation, radiation, and detection of THz ...

A novel 3D tomographic algorithm for short range cylindrical geometries using UWB frequency range is presented. The algorithm has been applied to breast tumor detection,
nevertheless, its non application-specific character ...

In this paper a complete UWB Circular
Tomographic System robust to high contrast or large objects, applied to Breast Tumor Detection, is presented. The main
contribution of this paper is to focus on the implementation ...
